Patent CA-2164714-C (CA)
Title: Composite, method and apparatus for making same
Inventor: DALTON ROBERT E
IPC: B30B5/06
Filed: 1994-06-15
Granted: 2003-09-23
Abstract: Methods of compression molding powdered polytetrafluoro-ethylene (PTFE) resins to produce composite articles having at least two distinct layers of PTFE resin, with each layer containing a different type of PTFE resin, are disclosed. A first layer of resin (100), preferably including a filter, is placed in a compression mold (200) and partially compressed at a relatively low pressure. A second layer of resin (102), preferably virgin (unfilled) resin, is then added to the mold and both layers are simultaneously fully compressed. After compression, the resulting composite preform is preferably sintered and coined to create a finished PTFE material or product. In a preferred embodiment, the partial compression step is performed at pressures of less than 500 psi. It has been found that modified PTFE resins provide improved resistance to cold flow and also provide better blending between filled and unfilled layers.

Patent CA-2171027-C (CA)
Inventor: HOETZL MAX
IPC: F27B3/22
Filed: 1990-12-19
Granted: 1997-10-07
Abstract: An  improved  industrial  furnace  employing a new  and unique heat transfer arrangement is disclosed.  The furnace is a closed end cylindrical chamber with a circular, concen-trically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into 8 heat treat chamber containing the work. The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing.   Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the beat treat chamber at slow speed.  Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good  heat  transfer  therewith.   The under-pressure opening causes the heated wind to contact the work before it is drawn into the under-pressure opening for recirculation. An incineration track is provided in the furnace insulation for incinerating the furnace flue products while also heat-ing the wind mass.

Granted: 2003-10-21
Abstract: A hydraulic drive apparatus for example for driving the header of a combine harvester includes a pump, at least one motor driven by the pump, a reservoir in which the hydraulic fluid is cooled and degasified and a hydraulic circuit connecting the elements. The pump is driven by a shaft of the combine which can be reversed for short periods of time for discharging blockages. The hydraulic circuit is arranged with check valves so that when operating in the normal forward condition it operates in open circuit arrangement including the reservoir. When operating in the reverse condition, the reservoir is bypassed and the fluid is directed in closed circuitcondition from the pump through the motor and back to the pump. This allows the drive apparatus to accommodate the necessary reverse condition for short periods of time using a simple hydraulic circuitry rather than the conventional mechanical drive arrangements.

Patent CA-2193601-C (CA)
Inventor: DEAN TODD
IPC: A43B17/03
Filed: 1996-12-20
Granted: 2007-04-10
Abstract: A hydrodynamic pad including fluid-filled inner and outer bladders interconnected by fluid channels and configured such that displacement of fluid from the center of pressure distribution generated by foot impact radiates from the inner bladder outwardly to the outer bladder through one or more of the fluid channels causing the outer bladder to expand to an expanded condition. The expanded outer bladder seats the wearer's heel in the hydrodynamic pad, thereby stabilizing the foot of the wearer, and the controlled flow of fluid through the fluid channels to the outer bladder dissipates the impact loads, thereby cushioning the wearer's heel. When the pressure is released from the inner bladder, by lifting the wearer's heel, the expanded outer bladder forces at least a portion of the displaced fluid to the inner bladder, such that the hydrodynamic pad is reinitialized.

Abstract: An incoming calling system of the present invention purposes to securely notify the user of the incoming to a radio portable terminal of a mobile communication unit or the like without disturbing others and decrease the probability of erroneous notification. Therefore, an incoming notification signal transmitter (24) for notifying the user of incoming can detect an incoming tone by inserting a jack into and connecting it with an earphone-microphone terminal (23) provided for a portable telephone (21) side and moreover, an incoming notification signal transmitter (24) is set to and supported by portable telephone (21). When portable telephone (21) receives an incoming call signal according to incoming calling from a base station (22), it generates a speech signal of an incoming tone and the speech signal is input to the incoming notification signal transmitter (24) through the earphone-microphone terminal (23) to detect incoming. The incoming notification signal transmitter (24) is constituted so as to generate incoming notification signal (25), transmit the signal to a card-type incoming notification signal receiver (26) or a wrist-type incoming notification signal receiver (27) by radio, and notify the user of incoming at portable telephone (21) side by vibration or a sound output buzzer.

Filed: 1997-06-18
Granted: 2005-06-14
Abstract: A method of a shared jackpot system of a gambling apparatus unit is provided, where the gambling apparatus unit comprises a plurality of coin-operated gambling machines. The gambling machines are linked to each other and jointly fill a jackpot. A predetermined part of the gambling bet of each gambling machine is employed to fill the jackpot. The filling level of the jackpot is displayed on each gambling machine and with a large display. A communication board is coordinated to each gambling apparatus in addition to a control unit. Upon actuation of the gambling machines, it is automatically determined which one of the gambling machines assumes the control in the form of a master. The master gambling machine monitors whether a jackpot trigger value is present. In case a jackpot trigger value is present, a command sequence is sent to all linked gambling machines. At the same time there occurs a final game in the gambling machines based on the command sequence. A rank sequence and a winning quota, respectively, is determined based on the predicted game result and the actual game result, wherein the rank sequence and the winning quota, respectively, represents a distribution key for the jackpot.
